Up/Down arrow on conflict window?

[Frankb]

That is a good approach I would have also recommended "Trigger Macro by Name". With a prefix you can narrow down the search. Maybe noisneil has another idea.

Another approach is the "poor man's stream deck". This works with KM and BTT.

Press and hold modifiers for one action?

I would like to use a shortcut (eg. ctr + a) to press and hold ctr + cmd + shift. Then I press an F-Key, action is triggered and the modifiers are released again. I don't know how to do this, can someone help? Thanks a lot.
